Final answer:
Good body alignment is needed when standing, sitting, or lifting to maintain proper posture, prevent discomfort or pain, and reduce the risk of injuries.
Step-by-step explanation:
Good body alignment is important in various situations, including when standing, sitting, and lifting. When standing, it is important to keep your feet shoulder-width apart, distribute your weight evenly on both feet, and maintain a straight posture to prevent any strain or discomfort on your joints and muscles. Similarly, when sitting, it is crucial to maintain a straight back, keep your feet flat on the floor, and support your lower back with a cushion if necessary, to promote good posture and prevent back pain. When lifting objects, it is essential to squat down using your legs and not your back, keep the object close to your body, and avoid twisting or turning while lifting to protect your spine and prevent injuries.
